膨胀和腐蚀

1.膨胀操作

 1 #include<opencv2/opencv.hpp>
 2 #include<iostream>
 3 
 4 using namespace std;
 5 using namespace cv;
 6 
 7 int main(int argc, char **argv)
 8 {
 9     Mat src = imread("D:/meinv.jpg");
10     cvNamedWindow("src_image", CV_WINDOW_AUTOSIZE);
11     imshow("src_image", src);
12 
13     //获取自定义核
14     Mat element = getStructuringElement(MORPH_RECT, Size(15, 15));
15     Mat out;
16 
17     dilate(src, out, element);
18     cvNamedWindow("dilate_image", CV_WINDOW_AUTOSIZE);
19     imshow("dilate_image", out);
20     imwrite("D:/learn-opencv/dilate.jpg",out);
21 
22 
23     waitKey(0);
24     return 0;
25 }
